Abstract
Present military requirements indicate a definite need for an auxiliary power unit with high specific output. In line with this objective, an initial feasibility study was conducted to develop a high output Model 4A032 Military Standard engine. By incorporating advanced design cylinder heads, pistons and valve train components, the maximum power output at rated speed was increased from the initial 9.8 bhp to 16.6 bhp with an accompanying reduction in fuel consumption from 0.85 lb/bhp-hr to 0.690 lb/bhp-hr, using military specification fuels and lubricants. These performance levels were achieved primarily by improved breathing and combustion characteristics of the engine. The results show the volumetric efficiency was increased from approximately 66% to 93%, an increase of 41%.
